The D-Link DSL-2740B Gateway with firmware EU_1.0, when an active administrator session exists, allows remote attackers to bypass authentication and gain administrator access via a request to login.cgi.

Multiple cross-site request forgery (CSRF) vulnerabilities in D-Link DSL-2740B Gateway with firmware EU_1.00 allow remote attackers to hijack the authentication of administrators for requests that (1) enable or disable Wireless MAC Address Filters via a wlFltMode action to wlmacflt.cmd, (2) enable or disable firewall protections via a request to scdmz.cmd, or (3) enable or disable remote management via a save action to scsrvcntr.cmd.
